Claims.

This invention relates to improvements in machines for use in setting up 'cellular cartons.

The main objects of this invention are:

First, to provide a machine for use in setting up Y cellular cartons of the type having transverse partitionsLthe lower en ds of which are disposed in slots in the bottom of the carton, which is simple and economical in structure and at the same time eiilcient in use. i f

Second, to provide a machine of the class described which is not likely to injure or distort the work.

Third, to provide a machine having the advantages above stated which requires little skill or eilort on the part of the operator.

Furtherl objects relating to detalls and econo,- mies of the invention will denitely appear from the description to follow. The4 invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompany- Fig. 1 is a perspective bodying the invention.

Fig. 2 is a fragmentary view partially in vertical Fig. 3 is a fragmentary view in transverse section on line 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary view partially in longitudinal section illustrating the parts in a partially completed work stroke with a carton within the machine.

Fig. 5 is a similar fragmentary view in partial section showing the parts inV completed work stroke position.

Fig. 6 is a fragmentary perspective view of a cellular carton in partially erected position ready for placing in the machine.

Fig. 'I is a fragmentary perspective view of the carton after the transverse partition members have been erected in the machine.

In the embodiment of the invention illustrated in the accompanying drawings the table I is provided with suitable supporting legs 2 supporting the table at suitable height for the convenience of the operator who stands or sits at the front of the table. Mounted centrally on the table is an upwardly facing tray-like holder 3 adapted to receive a partially erected cellular carton designated generally by the numeral I and to support it in upright position with'the side walls erected.-

The sides 5 of the holder have upwardly diverging inner surfaces to support the upwardly diverging side walls 6 of the carton.- The bottom members 1, 1 of the carton are inclined outwardly and the bottom 8 of the' holder is crownedl or shaped to support these bottom sections as clearly shown in the drawings. The bottom of the holder has transverse upwardly facing grooves or slots 9 therein adapted to receive the lower ends III of the ltransverse partitions Il when they are disview of a machine em'- posed through the slots I2 provided therefor in the bottom ofthe cartons, see Fig. 5.

In the steps of erecting the carton, when the Y side walls are brought to the position shown in Fig. 6 these transverse partition members Il lie in an approximately horizontal plane, see Figs. 2 and 6. When the carton is placed within the holder its left hand end as viewed in Fig. 2 abuts the left hand end of the' holder with the end cross portions I3 to which the end transverse partitions are hingedly connected in supported engagement with the ledges Il. see Fig. 2. As all of the transverse partition members are swung downwardly at one time considerable downward and endwiseA stress is applied, and these blocks sustain part of this stress.

Uprights i5 disposed at the ends of the holder have vertical slots I6' receiving the cross piece I1 at the upper ends of the slides I8. These slides are mounted in suitable slideways II provided in the housings 20 arranged on theouter sides of y the uprights. The lower ends oi! these slides i8 are connected by a cross bar 2| to which the foot lever 22 is connected by means of the link 23- and the lever 24. When this foot lever or treadle is moved downwardly the slides are carried downl-l wardly and consequently the cross bar I1 is carried downwardly, guided by the slots in thevup- Return springs' 25 .are provided, only one of which is partially illustrated.

The erector member 26 is mounted on the bar I1 for longitudinal sliding or reciprocating movement thereon. This erector member is provided with transversely spaced longitudinal rows of downwardly projecting forwardly inclined iingers 21, there being 4a linger for each transverse partition element. On the work stroke the bar I1 with the erector member thereon is carried downwardly, the erector member is brought into engagement with the fixed downwardly inclined actuating cam member al longitudinal movement as it completes the work stroke. This longitudinal movement, combined with the vdownward movement, eieetively swings the partition elements into their erected position and snaps their lower .ends through the slots in the bottom of the carton. the grooves 9 in the bottom of the holder permitting this action as clearly shown in Fig. 5.

28 which imparts to the erector 'Ihe fingers are preferably shaped and positioned to slightly bend the partition elements when the erector is at the limit of its downward stroke, insuring that the partition elements are engaged in the slots in the carton bottom. On the return stroke the opposite end of the erectormember comes into contact with the upwardly inclined return cam 29 which insures a reverse movement of the erector member and a withdrawal of the lingers from the carton without rupturing or straining the parts of the carton.

In use the operator partially erects the carton to the position shown in Fig. 6, places it in the holder, and` actuates the foot lever 22. As the parts are automatically returned the operator can lift the completely erected carton from the holder. Comparatively little eilort or skill is required in successfully operating the machine at quite high speed production.

No attempt has been made to illustrate or describe other embodiments or adaptations of the invention as it is believed this disclosure will enable those skilled in the art to adapt the invention as maybe desired.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent is:
